Hi Guy, 

I need some help, I am research the power tool.

and test the tool. I get the waveform

yellow is battery pack voltage waveform

red      is battery pack current waveform

In the black part, is the power tool at stall statues,and build the high current which is almost 100 amps.(the peak)

I have many question need to ask.

1. Can I measure the RMS current at black part section?

    It is possible at Oscilloscope DSO-X 3024T.

    if it can how can i use? I can't find the answer in DSO-X 3000 series manual.

2. What does the power tool Current Waveform is not a Direct current?

    that look like pulsating direct current. ? 

3. The waveform is noraml at Power tool?

    I used 14.4 DC motor, and the current is look like pulsating.

4. The Power tool is connect to The battery Pack ,

    At this waveform ,Could I know the current of Battery Pack are supply value?

    For the Battery pack,It is supply the DC (RMS) current value or The highest Current value?

    The Battery Pack is 14.4V 2.0AH , and the Waveform is used the Battery pack to Supply and get this waveform.

please help me this question , thx so much.

Part Number: MSP430-FLASHER

Hi Friend:

I want to use  MSP430-FLASHER (command line) to write *.hex to msp430afe253.

and before,i can debug code according to MSP-FET430UIF.(in IAR->FET Debugger's connection is ti USB-IF(COM7),and switch jtag to SBW interface).

but when i start uni-flasher,can't select com port(but usb 1---3),and can't get device's info.updateing firmware or driver is needed,etc.following is detail.

1)in command line,it is said that msp430.dll is missing.2)from UNIFLASH,just usb1-3 was showed.3)in IAR's configure,its shows com port.

4) inform me to do a firmware updated.5)when i press firmware updated,got error and driver is missing.

then another driver install is needed?

or some suggestion?

thx and best regards.

Using CCS + TExaSdisplay (someone knows why the upper/lower case is as it is? ) as per instructed in sekp066.pdf page 10 to 12, my TExaSdisplay display is dead.
The program is running fine, the LEDs are flashing (OK, I changed the delays so they become perceptible by a human being), so the problem is not there.
I got confirmation by TExaSdisplay that it found COM5 in my case, and it is the same USB cable that the one I got with the robot kit, so the cable and the communication should not be the problem.
But I don't get any clock signal (even with the event trigger set on raising edge for P1.0.
Any idea?  I even close CCS, just in case the debugger could interfere. No candy.

By the way, (another question, but highly connected) the sekp066.pdf mentions that we could use our own Logic Analyzer if we have one. Nice, thanks you to give the permission, :-) ,  but where would I pin, say on a scope, the probe to get P1.0 clock signal?  I don't see any pin with a remotely similar label on the development board.

Dear All,

This is vikash Chandra Raman, I am doing a project on MSP430F5529. I am interfacing ACS71020 ic with SPI Communications. I have to send 32 bit registers through Spi And also i have to recieve 32 bit data from ACS71020 on controller RXBUFF.

i have send 32 bit registers, through send functions, kindly check my send function.

sync_low;

send(0x2325,2),send(0x5626,2)

sync_high;

void send( int data,int i)
{
int l;
__disable_interrupt();
l=data;
l=l>>8;
while(i){
while(!( UCB1IFG & UCTXIFG));
UCB1TXBUF = l;
l=data;
i--;
}
while(UCB1STAT & UCBUSY);
__enable_interrupt();

}

It successfully send, But when i recieve the data it only recieve 8 bit , it is showing on RXBUFF.

So , i requested to say that if i have to recieve 32 bit data on rxbuff, what should i do.

kindly tell me the solution or give some ideas.

waiting for your positive response

I'm developing a small board with a MSP430G2230 and the TEST/SBWTCK is connected with a short track to a programming connector.

Is the internal pull-down resistor enough and the pin could be leaved floating, or is it better to add an external pull-down resistor to increase the noise immunity?

Thanks and best regards

Part Number: CC430F6137

Dear TI Team,

We developed a product based on CC430F6137 and attempted to build 4000 sets of them as a pilot run over last few weeks. Among the parts we build, we noticed that there were 93 PCS of them exhibited LCD display problem. Below is a description of the problem we observed for your reference.

1. Power up the device, CC430F6137 functions as expected and the LCD is turned on and shows correct information

2. While CC430F6137 is up and running, we tried to remove the system power to the device , and followed by applying power to device in succession, the LCD display suddenly switched off. Under this situation, we attempted to reset the device while keeping its power for multiple times , the LCD display kept on off state. What we expect is that the device should resume working after system reset.      

3. While the system was pending in a state as described in step 2. We kept on removing and applying system power to the device, there was chance that the system resumed working again - the LCD display returns normal and the system operate as expected. 

In summary, keep on applying and removing power to the device pushes a functional CC430F6137 device to a state where its LCD display was switched off and  system stopped functioning. We suspected that the issue we are experiencing may due to improper hardware design. Would you please help revise our schematic design as below and give us some hints where we could go wrong? Thank you.

Best regards,

Peter

Many of the examples in the new SDK v3.30 revision - which uses Sysconfig - contain a reference to "Board.h":

/* Driver configuration */
#include <ti/drivers/Board.h>

Is it correct to assume that this is an accidental carry-over from previous (non-Sysconfig) versions of the SDK? I expect that this should have referenced the new Sysconfig generated header file:

/* Driver configuration */
#include "ti_drivers_config.h"

Thanks,

Part Number: MSP430FR2311

Hi,

I want to use the transimpedance amplifer of MSP430FR2311IRGY  for my application. According to Table 6.22 (page 58) on datasheet given below TRIPSEL = 00 connects TIA+ input to P1.7, but other combinations (01, 10, 11) are not used.

However, according to Figure 6-3 on page 59 of the datasheet given below, to my understanding, TRIPSEL = 10 connects TIA+ input to Ground.

Basically I want to connect TIA+ input to ground and spare P1.7 for some other functionality. I am a bit confused on the use of TRIPSEL. My question is does TRIPSEL=10  connects the TIA+ input to ground or not?

Thanks very much in advance for your help.

Hi

I am trying to  configure BMI160 IMU's (sensor) registers and then read the information. Based on the BMI160 datasheet:

1- The read access should be like

 The read function based on above figure is: (First master transmitter->slave address->register address->repeated start->slave address->read data->...->NACK->Stop)

int8_t user_i2c_read(uint8_t dev_id, uint8_t reg_addr, uint8_t *reg_data, uint16_t len)

{
    int8_t rslt = BMI160_OK; /* Return 0 for Success, non-zero for failure */
    // Ensure stop condition got sent
    while (EUSCI_B0->CTLW0 & EUSCI_B_CTLW0_TXSTP);
    EUSCI_B0->CTLW0 |=EUSCI_B_CTLW0_TR;
    // I2C start condition
    EUSCI_B0->CTLW0 |= EUSCI_B_CTLW0_TXSTT;
    EUSCI_B0->I2CSA = dev_id;    //Set slave address 
    while((EUSCI_B0->CTLW0 & EUSCI_B_CTLW0_TXSTT));   //Wait for complete slave address to get transmitted

    while(!(EUSCI_B0->IFG & EUSCI_B_IFG_TXIFG0) ); //Wait until the data in TXBUF(register address) is transmitted
    EUSCI_B0->IFG &= ~(EUSCI_B_IFG_TXIFG0); //Clear the flag
    EUSCI_B0->TXBUF = reg_addr;    //Send the register address



       EUSCI_B0->CTLW0 &= ~EUSCI_B_CTLW0_TR;
       // I2C start condition
       EUSCI_B0->CTLW0 |= EUSCI_B_CTLW0_TXSTT;
       EUSCI_B0->I2CSA = dev_id;    //Set slave address 
       while((EUSCI_B0->CTLW0 & EUSCI_B_CTLW0_TXSTT) );   //Wait for complete slave address to get transmitted

       /* Read len-1 bytes of data*/
       for (i=len; i>1; i-- )
     {
           __delay_cycles(300000); // ~100ms pause between transmissions
           /*Read Data*/
         *reg_data = EUSCI_B0->RXBUF;
         reg_data++;

         /*ACKM*/
         while(!(EUSCI_B0->IFG & EUSCI_B_IFG_RXIFG0)); //Wait until the data in TXBUF(register address) is transmitted
         EUSCI_B0->IFG &= ~(EUSCI_B_IFG_RXIFG); //Clear the flag
         if(i==2)/*For the last byte send the STOP command*/
         {EUSCI_B0->CTLW0 |= EUSCI_B_CTLW0_TXSTP;}
      }
       /*Read the last byte*/
     if (i)
     {  
         __delay_cycles(300000); // ~100ms pause between transmissions
         while(!(EUSCI_B0->IFG & EUSCI_B_IFG_RXIFG0)); //Wait until the data in TXBUF(register address) is transmitted
         EUSCI_B0->IFG &= ~(EUSCI_B_IFG_RXIFG0); //Clear the flag
         /*Read Data*/
         *reg_data = EUSCI_B0->RXBUF; 
         reg_data++;
     }
     
     EUSCI_B0->CTLW1 |= EUSCI_B_CTLW1_STPNACK; //Sent NACK
     // Ensure stop condition got sent
     while (EUSCI_B0->CTLW0 & EUSCI_B_CTLW0_TXSTP);//check the ensure the STOP condition is sent out.

     return rslt;
    }

The problem I have here that the code get stuck in the 

 if (i)
     {  __delay_cycles(300000); // ~100ms pause between transmissions
         while(!(EUSCI_B0->IFG & EUSCI_B_IFG_RXIFG0)); //Wait until the data in TXBUF(register address) is transmitted
         EUSCI_B0->IFG &= ~(EUSCI_B_IFG_RXIFG0); //Clear the flag

My question is that did I write the correct format for read access?

Thanks

Hi all

    I used MSP430F6736A in my products ,when I used   FET por 430   to erase the internal storage space of MCU. I am prompted with an error. Please help me deal with it.

Part Number: MSP-FET430UIF

I reported an issue where CCS was unable to detect my MSP-FET430UIF and although I followed the recommendations which were given to me by TI support, I could not resolve this.

I am currently using MSP-FET430UIF together with a MSP430F4618 Experimenter board.

I am using an Ubuntu 19.10 laptop with the latest msp-elf-gcc toolchain (8.3.0.16)

After jumping through a number of hoops, I managed to get everything running correctly, using mspdebug and am now in the process of trying to configure my own custom Emacs-based IDE, with a bunch of packages, since CCS is a no-go for me and caused my laptop to crash.

I am now faced with an extremely ugly situation, whereby, it has become apparent to me that the MSP-FET430UIF tool has somehow damaged the bootstrap loader in the MSP430F2013 on the experimenter board.

I have read a number of articles regarding similar issues, in which it appears that the security fuse has blown, however, it is a matter of a mass erase of the on-chip flash being necessary.

Since the MSP430F2013 does not have a serial UART, the recommend methods of connecting a special circuit and correcting this issue, is not possible.

As a result, I decided to switch to a second, identical, brand-new MSP430F4618 Experimenter board.

Since my objective, at this stage, has only been to get my toolchain and debug environment working reliably, I have only used a simple blink.c to do my testing with:

#include <msp430x20x3.h>

int main(void) {
    WDTCTL = WDTPW | WDTHOLD;        // Stop watchdog timer
    P1DIR |= 0x01;                    // Set P1.0 to output direction

    for(;;) {
        volatile unsigned int i;    // volatile to prevent optimization

        P1OUT ^= 0x01;                // Toggle P1.0 using exclusive-OR

        i = 10000;                    // SW Delay
        do i--;
        while(i != 0);
    }

    return 0;
}

I was doing some testing, using MSPDEBUG as stub, and connecting GDB.

After a number of tests, setting breakpoints, running and just getting used to the commands and options, I noticed that, every time I loaded the blink.out and ran it, it looked like a breakpoint was set and was halting. I finally rebooted my laptop and power-cycled the board, to find that that the same thing has happened to my second experimenter board.

It is clearly evident to me that the damage has been done by some marginal timing issue, in relation to using the MSP-FET430UIF JTAG together the Spy-bi-Wire interface on the MSP430F2013.

The MSP-FET430UIF tool is revision 1.4a.

I would like to ask TI to please send me a replacement FET tool and two experimenter boards, which work reliably.

Thanking you in advance.

Please pardon the newbie question.

I am trying to power MSP430FR6043 IC using eZ-FET of MSP-EXP430FR4133 Launchpad. I have removed all the jumpers and connected all AVCC, DVCC, PVCC pins to 3V3 and all DVSS, PVSS AVSS pins to GND, as showed in picture. Also connected RST and TST pins to debug/program the MSP430FR6043 . Will this power up and flash the IC? Please help.
